FLOAT-VA LV E STECIFICATION forming part of l Letters Patent No. 793,629, dated July 4, 1905. Application filed October 6. 1904. Serial No. 227,331.

at Riverside, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Float-Valves, of which the following is a complete specification.

While this improvement is applicable to many of the various liquid-feed regulators, it is more particularly designed to be used in connection with cream-separators, in connection with which it is shown, the object being to produce a uniform feed of the milk to the bowl of the machine from a supply-tank of closed, as in an ordinary plug-valve.

varying head.

A further object of the invention consists' in the lowering of the supply-inlet relative to the machine, the desirability of which is? obvious, since the elevation of the supply` tank will be governed bythat of the supplyinlet.

Another object consists in combining the regulating mechanism with the cock or faucet which admits the milk to the machine.

Like reference-numerals refer to like parts throughout the several views.

-The preferred construction of this invention has been embodied in the mechanism as set forth in the accompanying drawings, in which- Figure 1 represents a sectional elevation of Fig. 2 is a plan section taken as indicated by the line a, a in Fig. 1. Fig. 3 is a detail view of the sleeve-valve and float in connection therewith. Fig. 4 represents a side elevation of the hollow plug and ioat-chamber, and Fig. 5 is a detail showing in side elevation the supply-inlet and the valve-v casing in connection therewith.

I am aware that it is not-new to regulate the supply of milk to a cream-separator by means of a ioat actuated by the overow into the oat-chamber; but what I claim, and believe to be new, is to actuate the regulating means directly by the Hoat in order to adjust the size of the supply-inlet, thus getting more immediate results, and hence a more uniform feed, than would be obtained if the outlet would be checked by means rendered operative by the submerging of a float.

In the drawings, 1 designates the supplyinlet leading from the supply tank or reservoir 2. On the delivery end of the supplyinlet is formed the valve-casing 3, of a barrel form, suitable for receiving the hollow conical plug 4:, which forms the receiving-chamber of the feed-regulating mechanism. The plug 4 is provided on one side with the opening 5, which communicates with the passage-way of the supply-inlet l when the plug is turned to proper position; but when turned to a nonregistering position the passage-way will be To the lower end of the plug 4 is secured the contracted nipple 6, the diameter of the discharge end thereof being of a diameter somewhat less than that of the supply-inlet 1. At the upper end of the hollow plug is formed the ioat-chamber 7, preferably of bowl shape and provided with the lid 8. Within the receiving-chamber formed by the hollow plug 4 are the two slight annular flange projections 9, which form seats or guides for the sleeve-valve 10. This sleeve-valve consists of a tube into which are cut, below the center thereof, the longitudinal slots 11, the function of the slots being to admit the liquid from the supply-inlet into the receiving-chamber. The sleevevalve 10 is longitudinally movable,` the longitudinal movement being effected by means of the iioat l2, which is secured to its upper end and which lies withinthe float-chamber 7. To limit the rotative movement of the plug and bowl and to enable the opening 5 to be readily brought to a registering or non-registering position with respect to the opening 5 in the supply-inlet, the stops 13 on the bowl 7 are made to contact the lug 14 on the supply-inlet, as clearly shown in Figs. 1 and 2.

The operation of the mechanism isA as follows: The reservoir 2 having been supplied with milk and the bowl and plug turned until the opening 5 is made to register with the opening in the inlet-pipe, the milk will be caused to raise in the oat-chamber 7 an amount depending uponthe excess in the area of the inlet-opening over the discharge-orifice and also upon the size and position of the slots l1. The size of the various openings is such that suiicient pressure will' be produced in the receiving-chamber to cause the liquid to rise in the float-chamber substantially to the height indicated in Fig. 1. In the position here shown the effective opening from the supply-inlet 1 into the receiving-chamber is less than half the total area of same, the tube l() having been lifted by the iioat 12 until only a small portion of the slot 11 remains in effectiveposition. If the head in the supplytank remains constant', the iioat and sleeve valve will remain stationary; butf'if the head changes, as it invariably does-growing less,

for instance-then the pressure in the receiving-chamber of the hollow .plug 4 will diminish, which will cause a corresponding fall of the liquid in the float-chamber 7 yIt is manifest that simultaneously with the fall of the lioat a greater extent of the area of the slots l1 will be exposed, the result being to immediately restore the normal pressure in the receiving-chamber. It is further manifest that the upward or downward movement of the iioat and the sustaining liquid therefor is simultaneous and in the same direction, thus effecting the adjustment of the supply-inlet opening direct and quickly as distinguished from that class of devices in which the liquid is made to fill and submerge or partially empty a iioat in order to effect the adjustment of the opening in the regulating mechanism. The last-described method is attended with fluctuations of pressure in the receiving-chamber more or less marked, which is largely overcome by the improved device constructed and operated as above set forth.

What I claim as my invention, and desire to 40 secure by Letters Patent, is-

1. In a iioat-valve, in combination, a supply-inlet having formed integral therewith a valve-casing, a hollow plug fitting into said casing, the said plug being provided with an opening which communicates with the said supply-inlet, a float-chamber formed upon the upper end of said hollowfplug, a valve fitted loosely vwithin said hollow plug and arranged to register to a variable extent with the said opening therein and, by the 4longitudinal adjustment of said valve, to regulate the amount of liquid admitted therethrough, and a ioat actuated by the overflow into said float-cham-V ber for effecting the longitudinal adjustment of said valve, substantially as set forth.

2. In a float-valve, in combination, a supply-inlet having formed integral therewith a valve-casing and an upwardly-projecting stopforminglug, a rotatable hollowplug fitting into said casing, said plug being provided with an opening which communicates with the said supply-inlet, stops movable with the said plug arranged tocontact the said lug on the valvecasing, a sleeve-valve iitted loosely within said hollow plug and arranged to register,"to a variable extent, with the said opening therein and, by the longitudinal adjustment of said sleeve, to regulate the amount of liquid ad- ,mitted therethrough, and a float actuated by` the overflow into the said float-chamber for effecting the longitudinal adjustment of said sleeve-valve, substantially as set forth.
